The platform being open all day does not mean all day is tradeable
Open a trading platform and you can click at almost any hour. Three in the morning included.
So most people conclude that time is not the problem.
That is exactly where the problem is. Being able to trade and being suited to trade are two different things.
Being able to trade is about whether the platform is open. Being suited to trade is about whether you can read what the chart is doing in that stretch of time.
You can click at three in the morning. What the chart is saying then, you probably cannot see — and you have work tomorrow.
